. l` do not claim siasiP AvAiLABLE con y racks may, if desired. be inadeinovable by providing a rack 235i` with rollers or casters 34, as shownin Fig. G of the drawings so as to be capable ot'lbeing wheeled into or ont of the main compartment provides an arrangement whereby the racks may be loaded or unloaded outside ot the main compartment,,such an yarrangement o racks being already well-known, and applied to various types ot' drying apparatus, hence,

to originate such a` construction, and merely lsuggest that it may be readily employed in my present novel drvin r apparatus.

I2.l`he reference character J indicates the rack rods which are straddled hetweeii the rails 6 of the racks, and upon which the macaroni `10 is suspended within the racks for drying.

`creased or decreased The rear end of the connnirtinent -l is closed by a novel constructionI of reguh table air controlling and directing means. rl his consists of a suitable frame-work or sup i which dividesl said end of the compartment into a plurality ot rectangular openings 12. Arranged within each opening 12 are a plurality ol piroted laterally entendingclourer-boards or slats 125,

porting structure 11,

all connected together by a suitable links rod 1st pivotally 1 secured lthereto, whereby said louver-boardsor slats 13 kot each open ing 12 may be adjusted by turning the saine pon their ypivots to open, close and regulate the saine to the passage of air through said openings 19a As shown in the drawings, the arrangement of said lonii'e'r-boards or slats lin each opening 12, is preferably similar to the ci'nistruction of the ordinary Persian blind, although it must. also he unl derstood Vthat other ways of mounting said regulatable louver-boards'or slats 13 may he, employed, such, for example, as a man- Iier of mounting similar to that provided h v the construction of Venetian blinds. Said louver-boari-ls or slats '13 .may he made ot any material desired, such as metal, wood, etc. The openings 12 may be niade of any desired area, and consequently may be inin number within the entire areay to be. closed thereby, as may be desired, or as may seein most `convenient and suitable to the location and size of the novel. drying apparatus.

The forward end ot saidcompartinent 11 is likewise closed by the, novel regulatable air controlling and directing means, compris-I suitable frame-work or supporting4 partment 4, said :framework or supporting 4, which thus` structure 11 is so combined or to provide a main door-opening 15 in which is hinged a door-frame 1G, the body of which is formed by said pivoted louver-boards or slats 15%; This main door-opening 15 gives access to the interionof said compartment, so that the inaierial to be dried may be taken therethrough into or out of the compartment 1. In addition to this main dooropening '15 there is also provided, in said frame-work or supporting structure, a very much smaller dooror wicket opening 17 in which is hinged a small door-trame 18, the body ot' is also formed by said pivoted louver-lniards or slats 13. This'small door or wiel-iet, thus provided, may be used by Vthe operator of the apparatus to enter the compartment el to observe the cliiects of the drying processes upon the material, and being barely large enough to admitb the passage of the person. the air currents and circulation is in no material degree disturbed by its use, as might he the case if the large inain door were used while the drying processes were heilig carried on.

lreferahly a lateral aisleor passageway ll.) is provided between each end of the compartment l, thus closed, and the adjacent rai-k, said aisles or passageways comninnieating with said llpigiludinal inain aisle or passageway S.

Located in the compartments or alleys 7, on each side thereof, so4 as to face theedjacent sides of the ma laroni supporting racks. and coextensive therewith are laterally extending trame-works or supporting slrnelnres 20, divided into a plurality of openings 21 in which arc-arranged pivoted laterally extendingleerer-boards or slats 32, those ot' each opening .21 being connected together by suitable linka-ods 23 piyotally Secured thereto. Finch' structures thus providing regnlatahle air controlling and directing means adjacent to each rack.

Located in each compartment or between the said air controlling anddirecting means above described, is an air circulating or driving-fan 24, rotatably mounted in hearings secured to opposite portionsot said frainwworks or supporting structures "20, in such a manner that said fans rotate laterally between the members of cach pair of rai-ks. Said fans may be driven by any suitable means irom a source of power either within or .without the com partn'ientl, although as illustrated the same are shown driven by a sprocket 26, over which runs the driving chain 27, extending exteriorly of said compartment flyto some suitable driring means. The fans 24e are preferably capable of rotation in either direction. l

In operating my novel drying apparatus the leerer-boards or slats 13, at the end of the compartment 1, are adjusted to provide alley T,

arranged aS 'BEsTAvAiLABLE cor of air therethrough, and at the sametime set in the proper inclination to produceI the desired. direction or air current.'` These adjustmen'ts having been made, the fans 2i are set in mtion,'with vthe result, that a` cur' rent of air` iscaused to flow through said compartiment 4, by virtue 'of the Vpropulsive effect of said fans, the same entering at one end thereof yfrom the outside atmosphere, vthen passing through the racks'in contact with the macaroni or similar material supported thereby, and thence outward' trom kthe compartment 4 through the opposite end roni, 'leaving a v considerable amount ofthereof.' In this manner 'adirect continuously flowing and constantly renewed current of airis passed in contact with the macaroni or the like, said louver-lioarils l and 22 tending not only to break the force .of the draft or current of air thus setin motion, so that a nottoo violent contaet\ thereof With the macaroni or the like occurs, which would tend to shatter or break the same, with consequent waste and loss,

but also tending to deflect the air from to straight a path of movement, and thereby force the same with proper distributive ef ect into contact with the entire mass ol macaroni .orthe like supported within the racks.'4 It will vthusbe apparent thatthe moving stream or current-ofair thus gently maintained'in contactl with the macaroni or ftheilike will serve not only to absorb the "affect the same, but such tendency totoov rapid drying may bel quickly checked/by' regulating and yadjusting the several sections ot louver-boards orslats13 and '22, to*

` properly obstruct a too rapid flow of the' air. In this respect my apparatus is capable of great flexibility vof adjustment, since the louver-boards or slats 13 and Q2 are arranged in independently adjustable sehtions. For example, the entrance of the air at one end of the compartment 4i mayybe obstruct-L ed, while its eXit jatther other end of the same is expedited, or v ice versa, by means of opposite abjustment of the lo'uveeboards or slats 13, or ifone portion of the macaroni or the like, as supportedin thel racks, is drying more rapidly than another portion, tlien the louver-boards or slats 13 and 229fthe openings opposite or 4nearest yto the quickly drying portion may be closed to divert the air current, more directly tothe slow-drying portions through the remaining open 4, and-preferably within vthe inner coni louver-boards or slats, and so on. all accordmg, to the conditions lpresented by each batch Otinaterial to be dr1ed. The fans Qt yalso being "reversible in action, the dircc tion of the air current may be reversed so thatall sides ot' the macaroni or the like may. receive uniform treatment.

l alsoprovide within the compartment partaient or alleys 7,'stean1 radiators 28, or other suitable heating units. which may'A be utilized to raise the temperature ot' the air to `eti'ectquicker drying., l'

ln. drying macaroni or the like, the process usually divides itself "into two or more drying periods; During the first period the air currents tend to absorb and carry oil' themoisturenearest the surface of the macamoisturegwithixr the internal parts or cori` of thedough. It', after this surfacey drying hasbeen accomplished to a proper .legree, theair currents are continued 4the surface of the macaroni or' the like becomes too-dry, tends to crackand ycrumble away trom the still moist internal parts or core, and theretore quickly ruins the batch. Consequently the-drying aircu'rrents must be stopped and the macaroni or the like inclosed lin quiet air for a time sulicent to permit the inoisture in the internal parts or core of the dough-'to come to the surface, after which ythe `second drying period; may be inaugurated by renewing the ilow 'of the. air cui rents, and thisk interruption of the airrur- 10o rents may be required several times accord- `ing. tothe conditions. Under these requirementsof proper drying my apparatus readily lendsitself to 'the proper inclosinpl of the Amacaroni or the like during the rest`105 periods without necessity ot handling or removing the same from the supporting'racks, since all that is Jnecessary to be done is to close fully said louver-boards 13 and22 and stop the fans 24, thereby safely and properly 'confining the macaronimr the llike in still air until the inner moisture comesto tlnl surface thereof, andfit 1s aga1n-proper to 'continue the drying process, by renewingr the air currentsin contact therewith.

WVhile` it'is preferable to employ vthe fans- 24 within the compartment 4, as above described, and shown in the ,l rawings,it

must be understood that the scope of my inl vention, so far kas it applies broadly to thc 20 u se of the louvcr-boards or slats 13 and 22 for controlling` and 'regulating the air cur- Arents passed through thev compartment 4 in contact with the material racked therein,

.is intended te include any method or means '125 for generating andv circulating air currents through said compartment 4, vWhether said air currents be generated Within the ycompartment, or Without said compartment and thence directed therethroggh.

Referring now to Fig.'5 of the drawings, I ha-ve illustrated therein my novel drying apparatus constructed substantially as above described, as is indicated by the similar refer-` ence characters applied thereto, but equipped with a slightly modified construction of?- macaroni, spaghetti and the like, I have here shown a rack construction for the support of small cut alimentary paste products such as noodles, short lengths, etc., the same comprising suitably disposed vertical standard members or supports 29, between which 'extend supporting rails 30. The said standards or supoprts 29 are arranged opposite each other, so as to dispose opposite each other in like manner, said supporting rails 30. The supporting rails 30 of the inner side of the racks, however, are positioned in a horizontal plane somewhat higher than the opposite supporting rails of the outer sides of the racks. Consequently each pair of oppositely positioned supporting rails 30 are adapted to support a tray 31, havingan open mesh bottom 32, in a slightly downwardly and 'outwardly tilted or inclined position, which affords the best arrangement for supporting the paste in proper exposure to the air currents directed through the openings between the louver-boards or slats 13 and ll am aware that some changes may be made in the arrangementsand combinations ot the various devices and parts, as Well as in the details of the construction of the same, without departing from the scope of the present invention as set forth in the vforegoingspecification, and as defined in the claims appended hereto. I'Ilence,I do not limit my invention to the exact arrangements and combinations of the several devices and parts as described in the foregoing specification, nor do I conline myself to the exact details of themmstrnction of the said parts as illustrated in the accompanying drawings.
